CARGO VESSEL.

Implication filed January 6, 1921.

T (a l whom "it my, concern Be it known that I, WALTER LAMBERT, a subject of the King of Great Britain, and residing 14: Place ltoyale, in the city and district of lliont in the Province Que bec, in the 1 ion of Canada, have invented setul Cargo Vessel, of which the 0. is the specifics tion The ion relates to ca vessels as described in the present speciicat-ion and illustrated in the accompanying drawings that form part of the same.

The invention consists essentially in the novel const' c 'or whereby the discha "e of bulk cargo than water, is facilitated by the par ici cross-sectional shape 0*- side wal l is d tho-c. The obj ts 0 tate the disch the invention are t or cargoes like pulp- Wood so that much the vessel thereb time will be saved and permitted to make so many more trips duri. the season; to economize in the oi unloading expenses by using natural facilities, and consequently float the cargo out of the hold, which will materially decrease the expenses of labor in the handling of the wood; and generally to provide a staunch and reliable cargo vessel which may be readily discharged of its cargo at its destination.

In the drawings, Figure 1 is a side elevation of the vessel.

Fig. 2 is a plan view showing the cargo space, the bulkheads, and the air-tight compartments separating the hold into its divisional arrangement.

Fig. 3 is a perspective detail showing, in skeleton form. the divisional arrangement as illustrated in the plan view in Fig. 2.

Fig. 1 is a fragmentary sectional detail 0; the side wall and coaming in lip form.

Fig. 5 is a fragmentary sectional view of the side wall at an intermediate point between a bulkhead and the middle training of a cargo compartment.

Fig. 6 is a cross-sectional view illustrating the operation of discharging the cargo.

Like numerals of reference indicate corresponding parts in each figure.

Referring to the drawings, the hull 1 is built up from the bottom 2, around the arc iraming formed o1 the vertical beams 3,-

flaring bulwarks 9, having the downwardly turned lips 10.

The rubbing strips 11. extend along the sides just below the knees 12 of the vertical beams 8.

The stifiening brackets 13 are arranged between beams and bulkheads, and the guiding plates 14 facilitate the passage of the wood over said brackets.

The vertical beams 3 are joined just below the bulwarks 9 by the upper transverse girders 15, and these transverse girders are midway between the bulkheads 5 of each cargo space.

The end walls of each cargo space are the bulkheads 5, and these bulkheads form the open compartments 17, which extend upwardly to the bulwarks 9, and are throughout completely clear of covering so that he hull is an open boat between the machinery at the stern and the crews quarters at the bow.

The walking bridge 19, is built centrally over the bulkheads 5, and is substantially flush with the said bulkheads, and is supported interinediately by the transverse girders 15 on the brackets 20.

The monitor track 21 is secured to the walking bridge 19 and the hose line guides 22 are arranged between the rails of said track and on this track a monitor 23 travels and carries the swinging nozzle 24. connected to the hose 25 in the said hose guides 22, and connected to any water under pressure.

The flooding pipe line 31 is connected to a pump 32, operated by the machinery or the vessel or in any suitable way, and runs along the bottom of the vessel throughout the whole length of the open cargo space and is fed by said pump 32, which draws the water to the pipe 31 and forces it out of one or more ports closed by the valves 33 operated by the wheels 3 1- from the walking bridge 19.

The main discharge pipe 35 runs along the bottom of the cargo space through the several open holds and is connected to a pump 36 which draws the water from the holds through the ports closed by the valves 37 the latter being operated by the wheels 38 from the walking bridge 19.

The doors 39 swing on hinges 40 and open a discharge for wood through said bulwarks though most of it will float over yet considerable will be carried through the openings made by throwing these doors down, as there is a rush of water from the discharging compartment. and this rush of water will serve 'to carry the wood with it.

In the operation of this vessel, it will be seen that the hull, with the exception of a short space at the stern for the machinery and ofiicers, and a short space at the bow for crew and landing facilties, is taken up by the cargo space; in fact, it is practically a large open boat between ends, with no hatches though necessarily the hull must be strengthened intermediately by a transverse framing; and also bulkheads for dividing the cargo space up into holds, so that the operation of discharging may be done one at a time to guard the safety of the vessel.

The wood is loaded into these holds in the well known manner familiar to the transportation of such cargoes, and is piled as high up as possible without running the risk of losing it. A hold of the vessel is flooded when it arrives at its destination, preferably one at a time, so as to avoid any danger of capsizing, and to avoid excessive trim while the discharge is being made.

The water in the flooded hold will carry the wood to the top of the bulwarks and thereover, though most of the wood will pass through the openings cleared by swinging the discharge doors downwardly. As soon as the wood is discharged from any one hold that hold is emptied, that is to say, it is pumped out and cleared of water, and the same operation is carried out with the next hold, and so on until they are all cleared; of course it may be possible to clear two or three at once; in fact, as many as the conditions in discharging will permit, the main object being to clear the cargo space of the wood by natural means' i What I claim is:

1. In a cargo vessel, a hull having side walls converging from a point intermediate of their height and flaring at their upper ends and terminating in a downwardly turned lip, transverse bulk heads and frames bracing said sides and leaving an open hold from the said sides inwardly and means for driving the floatable cargo over the flaring sides movable longitudinally of the vessel.

2. A cargo vessel having a plurality of partitions and transverse framing dividing the cargo compartment of a hull in open boat formation, a walking bridge over said compartment from end to end, a monitor travel ing on said bridge and having nozzle therefrom and water connections to said monitor supported by said bridge.
